…		…
1	Revision history for Perl extension Coro.	1	Revision history for Perl extension Coro.
2		2
3	3.0	3	TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
		4	TODO: maybe implement a default message channel, very much like Erlang's
		5	actor model (which is cool in a lot of important aspects (failures!),
		6	but very lacking in others (higher level ipc)).
		7
		8	TODO: Coro::AnyEvent
		9	- completely reworked the Coro manpage.
		10	- added Coro::AnyEvent, generic event loop integration.
		11	- implement cancel, ready and kill commands in Coro::Debug.
		12	- document find_coro in Coro::Debug.
		13	- incompatible change: rename has_stack to has_cctx.
		14
		15	4.6 Sat Apr 26 10:05:14 CEST 2008
		16	- INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
		17	by the Coro module. It was a mistake to have it in the first place.
		18	- (experimental) support for activestate perl 5.10 (method "w").
		19	- (experimental) support for strawberry perl (method "a").
		20	- coro_sigelem_set did not return a value although it had to,
		21	actual impact unknown.
		22
		23	4.51 Mon Apr 14 13:28:27 CEST 2008
		24	- make it compile again on 5.8.
		25
		26	4.50 Thu Apr 10 09:43:17 CEST 2008
		27	- I did it twice! (see 4.49).
		28
		29	4.49 Sun Apr 6 21:23:31 CEST 2008
		30	- grr, instead of compiling the recent changes on 5.10 only they
		31	were compiled on 5.8 only.
		32
		33	4.48 Sun Apr 6 20:36:46 CEST 2008
		34	- allow coroutine switches during eval's under 5.10.x, as it seems
		35	the parser is a per-interpreter option now, so this is safe
		36	(this might fix the odd crashing bug).
		37	- drop support for 5.9.x versions: they are dead, jim.
		38
		39	4.47 Sun Apr 6 00:37:52 CEST 2008
		40	- force cctx allocation on API calls: we know we need to force one
		41	and gcc actually manages to confuse our heuristic nowadays,
		42	leading to crashes and worse.
		43	- document force_cctx.
		44
		45	4.46 Fri Apr 4 22:05:43 CEST 2008
		46	- upgrade libcoro, resulting in pthread-backend (which was only created
		47	to fulfill the rules of the programming languages shootout).
		48
		49	4.45 Thu Mar 13 11:55:36 CET 2008
		50	- fix a file leaking bug in eg/mhyttpd that would allow
		51	downloading of any file (reported by oesi).
		52	- fix deadlock bug in Coro::Channel (reported by Richard Hundt)
		53	(also add testcase).
		54	- support Broadcast option in Coro::Socket (patch by Richard Hundt,
		55	apparently having loads of fun with that).
		56	- implement $state->swap_defsv, ->swap_defav and document ->throw.
		57
		58	4.4 Wed Feb 13 16:44:29 CET 2008
		59	- only assume .cfi pseudo isns exist on GNU/Linux.
		60	- add get_timed method to Coro::Channels.
		61	- fixed Coro::Debug manpage.
		62	- perl 5.11 compatbility improvement based on patch by
		63	Andreas König.
		64
		65	4.37 Sun Jan 20 11:25:23 CET 2008
		66	- soften the check for an active parser for perl 5.10 (avoiding
		67	"Coro::State::transfer called while parsing" in many cases).
		68
		69	4.36 Sun Jan 13 10:53:56 CET 2008
		70	- reset diehook when terminating from an async_pool as to not
		71	trigger any __DIE__ handlers.
		72
		73	4.35 Sun Jan 13 04:14:13 CET 2008
		74	- "bt" debug command now displays any exceptions
		75	from longmess and also skips the innermost
		76	stackframes, giving more useufl output.
		77	- allow backtraces in coroutines blocked in Coro::EV,
		78	at a <1% speed hit.
		79	- handle localising of $SIG{__WARN__} and __DIE__
		80	properly (with a proper amount of dirty hacking).
		81
		82	4.34 Sat Dec 22 17:49:53 CET 2007
		83	- upgrade to EV version 2.0 API.
		84
		85	4.33 Mon Dec 17 08:36:12 CET 2007
		86	- make Coro::AIO etc. loadable in the absence of EV.
		87
		88	4.32 Mon Dec 17 07:46:02 CET 2007
		89	- majorly improved Coro::Handle's performance with Coro::EV.
		90	- implemented the until now mythical Coro::BDB module.
		91	- specialcase EV in Coro::AIO and Coro::BDB for extra speed.
		92
		93	4.31 Wed Dec 5 12:32:39 CET 2007
		94	- remove warn statement form Coro::Util.
		95
		96	4.3 Tue Dec 4 20:33:14 CET 2007
		97	- calls to the idle function could cause stack corruption
		98	when the stack changed.
		99	- do no longer rely on the presence of EV::DNS if EV is used
		100	(because it is gone), but instead take avdantage of EV::ADNS
		101	if available.
		102	- add ($) prototypes to all functions in Coro::Storable.
		103	- use a conventional (safer) idle callback in Coro::EV.
		104	- do accept quickly in Coro::Debug to avoid endless loops.
		105
		106	4.22 Fri Nov 30 16:04:04 CET 2007
		107	- really use optimised versions for Event and EV in Coro::Util
		108	and Coro::Handle.
		109
		110	4.21 Sun Nov 25 10:48:59 CET 2007
		111	- fix a spurious memory read.
		112	- Coro::EV no longer keeps the eventloop "alive".
		113
		114	4.2 Fri Nov 9 20:47:05 CET 2007
		115	- enable/disable tracing from a new coroutine, not a pooled one.
		116	- fix a memleak in Coro::Event.
		117	- removed killall call from fork_eval.
		118	- made sure store_fd is already loaded so that fork_eval
		119	does not have to parse autoload in each subprocess.
		120	- only use assembly method if -O switch is in $Config{optimize}.
		121	- add (optional) Coro::EV module, so far the best event loop module
		122	directly supported by Coro.
		123	- if the event model is EV, use EV::DNS to resolve
		124	stuff in Coro::Util.
		125	- don't get confused by multiple event notifications in Coro::Handle.
		126	- initial support for EV (libevent interface).
		127	- require Event and EV using configure_requires, to force their existance.
		128
		129	4.13 Wed Oct 24 07:26:45 CEST 2007
		130	- add Coro::Storable::blocking_thaw.
		131	- use a vastly more complicated technique to localise
		132	$SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
		133	- use a coroutine for the idle callback Coro::Event,
		134	instead of running Event in the current coroutine context.
		135	This also catches recursive invocations.
		136	- actually report fork errors in gethostbyname and inet_aton.
		137
		138	4.11 Thu Oct 11 02:40:24 CEST 2007
		139	- port to threaded perls.
		140
		141	4.1 Thu Oct 11 02:38:16 CEST 2007
		142	- incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
		143	be local to each coro (see Coro::State).
		144	- incompatible change: for very deep reasons, cede and cede_notself
		145	cannot return anything, so nothing will be returned.
		146	- possibly bring back 5.10 compatibility (untested).
		147	- work around stupid (and wrong) warning on 5.10 :(.
		148	- overlay the saved state over the context stack. This saves
		149	a few hundred bytes per coroutine on average and also
		150	speeds up context switching a bit.
		151	- further tune default stack sizes.
		152	- (more) correctly calculate stack usage in coro_rss.
		153	- Coro::Storable::blocking_* did not properly lock
		154	resulting in races between coroutines.
		155	- added Coro::Storable::guard.
		156	- stopping to trace a coroutine could destroy the cctx of
		157	an unrelated coroutine.
		158	- explain the relationship between Perl and C coroutines in
		159	more detail in Coro::State.
		160	- Coro::Util::inet_aton did not short-circuit dotted quad forms,
		161	causing a fork per resolve. This also affected Coro::Socket.
		162	- switch to a separate stack in $coro->call/eval to avoid
		163	invalidating pointers.
		164
		165	4.03 Sat Oct 6 21:24:00 CEST 2007
		166	- added Coro::throw method.
		167	- minor code cleanups.
		168
		169	4.02 Sat Oct 6 02:36:47 CEST 2007
		170	- fix a very minor per-coroutine memleak (a single codereference).
		171	- fixed a bug where the currently in-use c context would be freed
		172	prematurely (can happen only when programs change the stacksize
		173	or use tracing).
		174	- tracing can no longer keep a coro alive after it terminated.
		175	- do static branch prediction in the common path for gcc. gives
		176	about 2-5% speed improvement here.
		177
		178	4.01 Fri Oct 5 22:10:49 CEST 2007
		179	- instead of recreating a standard output handle we simply
		180	use STDOUT, which is faster and hopefully more robust.
		181
		182	4.0 Fri Oct 5 12:56:00 CEST 2007
		183	- incompatibly changed Coro::Storable::freeze.
		184	- major new feature: added Coro::Debug, for interactive coroutine
		185	debugging, tracing and much more.
		186	- major bug fix: unbelievable, but true: $_, $/ and many other
		187	"saved" variables actually weren't being saved. This has been fixed,
		188	of course, while increasing performance while losing all the save
		189	flags.
		190	- save flags are gone, and all the api functions dealing with them.
		191	- added Coro::Semaphore::adjust.
		192	- added Coro::Util::fork_eval.
		193	- added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
		194	- added Coro::killall.
		195	- reduce initial stack sizes to allow for "micro-coroutines".
		196	- better async_pool resource management, moved parts of async_pool
		197	handling to XS (major speed improvement).
		198	- actually croak before modifying important data structures.
		199	- refuse to transfer while compiling.
		200	- possibly support eval EXPR better now.
		201	- enable assembly per default on linux+bsd x86+amd64.
		202	- all internal members were renamed _something for easier subclassing.
		203	- many minor tweaks.
		204
		205	3.63 Wed May 16 14:10:06 CEST 2007
		206	- implement handcoded assembly for x86/amd64 SVR ABI.
		207
		208	3.62 Fri Apr 27 21:36:06 CEST 2007
		209	- upgrade libcoro (which might set unwind info correctly).
		210	- change default on linux to setjmp/longjmp.
		211
		212	3.61 Thu Apr 19 12:36:18 CEST 2007
		213	- Coro::Storable caused an endless loop when thawing invalid
		214	pst's sometimes.
		215	- use a Semaphore in Coro::Storable, as Storable doesn't
		216	seem to be reentrant (although it is documented to
		217	be threadsafe...).
		218	- fix Coro::Signal to bring back the original unreliable
		219	but stateful semantics.
		220	- fixed a lot of typos in Coro.pm (patch submitted by David
		221	Steinbrunner, which applied flawlessly).
		222
		223	3.6 Sat Apr 14 17:13:31 CEST 2007
		224	- added some bugfixes to get eg/myhttpd working again.
		225	- added Coro::Storable for often-cede'ing freeze/thaw.
		226	- try to do a clean exit when a coroutine calls exit
		227	(EXPERIMENTAL).
		228	- got rid of indirect call through _coro_init.
		229	- updated the partly antique examples in eg/ to
		230	work again and be a bit less magic, too.
		231	- fixed Coro::Signal semantics to work as documented again.
		232
		233	3.55 Sun Mar 25 01:20:47 CET 2007
		234	- add SAVE_DEFFH to save the default filehandle and enable
		235	it by default.
		236	- finally move socket-operations from Coro::Socket to Coro::Handle
		237	to be able to unblock foreign sockets.
		238	- add Coro::State::save_also and guarded_save.
		239	- add count accessor to Coro::Semaphore.
		240	- add Coro::State::cctx_stacksize.
		241	- just for the fun of it, do not rely on implicit context,
		242	which can dramatically improve performance, but people
		243	using windows-process-emulation perls do not care much about
		244	performance.
		245
		246	3.51 Sun Mar 4 14:18:04 CET 2007
		247	- fixed a problem when you weakened references to Coro::State's
		248	(patch by Yuval Kogman).
		249
		250	3.501 Wed Feb 28 12:44:07 CET 2007
		251	- rename some global symbols as macosx from hell redefines
		252	them without asking.
		253
		254	3.5 Tue Feb 13 20:22:53 CET 2007
		255	- do AnyEvent model detection earlier, avoiding problems
		256	caused by first using AnyEvent and later Coro::Event.
		257	- implement and document Coro::Event event objects.
		258	- fix a potential problem in Coro::Event causing crashes.
		259	- initialise PL_comppad when creating a new coroutine,
		260	avoids crashes on early coro destruction.
		261
		262	3.41 Mon Jan 22 19:19:49 CET 2007
		263	- readline on Coro::Handle did not support undefined $/,
		264	nor did it deliver partial lines on EOF or error.
		265	- implement malloc fallback for stack allocation because
		266	stupid broken idiotic OSX has a stupid broken
		267	idiotic fits-the-whole-os mmap "implementation" and
		268	my dick feels longer if Coro is portable even to
		269	obsolete platforms.
		270
		271	3.4 Fri Jan 19 21:52:54 CET 2007
		272	- remove t/09_timer.t, as it isn't really testing much
		273	but was rather flaky in practise.
		274	- async_pool coro would keep arguments and callback alive until
		275	it was reused.
		276	- cancellation of a coroutine could cause spurious idle calls
		277	in cede_notself.
		278
		279	3.3 Sat Jan 6 03:45:00 CET 2007
		280	- implement $coro->on_destroy.
		281	- Coro::Event blocking semantics have been changed,
		282	documented and - hopefully - improved.
		283	- fix nice adding, not subtracting, from priority.
		284	- fix ->prio and api_is_ready (patch by Mark Hinds).
		285	- fixed an assert ("... == prev__cctx->idle_te")
		286	that could errronously trigger.
		287	- fix various large and small memleaks.
		288	- use a (hopefully) more stable cancel implementation
		289	that immediately frees the coroutine data.
		290	- cede/cede_notself return a status now.
		291	- added Coro::guard function.
		292	- added a global coroutine pool for jobs (on my machine,
		293	I can create and execute 48k simple coros/s with async,
		294	and 128k coros with async_pool).
		295	- Coro::AIO now uses the coroutine priority as io priority.
		296
		297	3.2 Fri Dec 22 05:07:09 CET 2006
		298	- improve portability to slightly older perls.
		299	- use cleaner coroutine destruction.
		300	- simplify configuration for users.
		301	- optionally (unrecommended) prefer perl functions over
		302	their coro replacements.
		303
		304	3.11 Tue Dec 5 13:11:24 CET 2006
		305	- fixed some bogus assert's, but as perl.h disables assert even
		306	without NDEBUG (thank you very much), not too many people should
		307	notice (that did include myself). Andreas König noticed, though :)
		308	- do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
		309	it. Also noticed by Andreas König :)
		310	- save/restore tainted status.
		311	- verified to pass the testsuite on my 5.9.5.
		312
		313	3.1 Mon Dec 4 23:03:40 CET 2006
		314	- INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
		315	- incompatible change: transfer flags are now per-state.
		316	- give a better error message on deadlock.
		317	- document Coro::nready.
		318	- enhanced testsuite.
		319
		320	3.01 Sun Dec 3 23:47:42 CET 2006
		321	- forgot to include Coro::Timer.
		322
